Development and validation of morphological segmentation of age-related cerebral white matter hyperintensities
چکیده انگلیسی
Automated morphological segmentation combined with an adaptive boosting statistical classifier showed substantial agreement with manual segmentation, with an intraclass correlation coefficient (ICC) of 0.90 (95% confidence interval [CI], 0.80-0.95) for WMH volume and median similarity index (SI) of 0.58 (interquartile range [IQR] 0.50-0.65). The method also showed similarly high levels of agreement with semi-automated segmentation, with ICC 0.92 (95% CI 0.89-0.93) and median SI 0.56 (IQR 0.49-0.66). Its best performance was observed for the highest tertile of WMH volume. Threshold-based and Gaussian mixture model-driven automated segmentation generally did not perform well in this study.
